the fact that there is an history of racism behind ethnicity-based research does NOT mean that we will never be able to conduct any research, or postulate theories that will have to be proved or disproved. Your demand for totally outrageous conditions for performing research (genetically modify people …) thinly masks the fact you do not want ANY research that might find a difference between ethnic groups. BTW I am not claiming that such difference exists or was proved in this case; but I am annoyed at the attempt of muzzling any discussion of these subjects by raising the "racism" flag. At some point I believe this is self-defeating, and will contribute to more people believing in this.

as for this:

"Specifically, I have yet to see a study examining the genetic cause of why White athletes tend to dominate at water polo, swimming and diving, and other stereotypically "White" sports"

Very weak, my friend. All these sports, as has been pointed time and again, need MONEY which does not exist in poor, non-white countries, nor in poor, non-white population areas in developed countries.
